In the FILES section of this template you'll find a folder of readings, organized into topical folders of "possible readings". Some of these are already embedded in the existing modules as a starting point, but can be exchanged for others, either from the cache or your own additions. These include:
There is also a file folder titled "Background Reading for Instructor, If Needed"; it's provided in case you want a refresher on some concepts. The pdfs are not accessible, so shouldn't be shared with students, but could be used to inform your lectures or answering questions.
New examples to include in these would be welcome!
